It sounds like you’re describing resolve and what one may call grit (“courage and resolve; strength of character”).
These are beneficial qualities for success for sure!
I just write to suggest also to keep sincerity in mind. Rather than ‘my’ intent, I think sincerity trumps that even more. Sincerity will naturally lead to the doing of the thing that you want to do.
Sincerity is what will lead to you breaking through the fog. It’s what allows you to perceive there is a fog in the first place (instead of denying it exists). And it is what allows you to see that you want to actually do something about it.
So ramp up that sincerity! Observe yourself, be aware of yourself, and you will see that sometimes the fog lifts and sometimes it gets denser. Sincerity will then allow you to see what happened to lead to the fog lifting and what happened to lead to the fog thickening. You will sincerely see why the fog got thicker. You will sincerely see specifically what you did thought or felt such that you went deeper in the fog. Then you will sincerely be able to see that you would rather change that about yourself - and thus lift the fog a little bit - rather than continue with the habitual pattern that leads to the thicker fog.
And then you rinse and repeat and the fog will gradually get lighter over time
